Then there’s the story of David and Nathan Zellner, filmmaker siblings from Austin, who prove that starry-eyed Sundance still embraces deeply idiosyncratic work made on a shoestring budget. After screening some of their short films at the festival, the filmmakers introduced their eccentric debut feature, “Goliath,” there in 2008. A comedy about an aimless thirtysomething (played by David) whose life begins to come unglued after his cat goes missing, “Goliath” received encouraging reviews and eventually secured a video-on-demand and DVD release through IFC Films.
But the brothers didn’t immediately book one-way tickets to Los Angeles. Instead, they chose to remain in Austin, where they continued to make shorts and direct music videos for their favorite local bands.
